AI Technical Summary
Existing vacuum lifting machines have stability and safety issues when handling materials with a shifted center of gravity. This is especially true when the items are long and have a shifted center of gravity, as the crossbeam can cause the frame to deflect, affecting operational stability and potentially leading to safety accidents.
A vacuum suction lifting machine with adaptive rotation function was designed. By setting a mounting base and bearing at the bottom of the frame, the crossbeam can be rotatably installed. The rotation of the crossbeam is restricted by fixing pins and limiting pins, so as to achieve adaptive rotation and angle adjustment and ensure the stability of the center of gravity of the object.
It improves the stability and safety of vacuum suction lifting machines when handling materials with a shifted center of gravity, enhances operational flexibility and reliability, and reduces safety hazards.

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the utility model will be further explained in detail below with reference to the drawings and specific embodiments.

[0025] The vacuum suction crane of the scheme has three states:
[0026] (1) self-adaptive rotating state: the fixed bolt 5 is taken out of the fixed slot, and the limiting bolt 6 is taken out of the limiting slot at the same time, at this time, the beam 2 is not limited and freely rotates, so that when the center of gravity of the suctioned and hoisted object deviates in the axial direction perpendicular to the beam 2, the beam 2 can be self-adaptively rotated to the stable center of gravity, thereby ensuring the operation reliability of the vacuum suction crane.
[0027] (2) fine angle limiting state: the fixed bolt 5 is taken out of the fixed slot, and the limiting bolt 6 is arranged in the angle limiting hole and inserted into the limiting slot, at this time, the beam 2 can be rotated in a small range, so that the hoisted object can be pushed to fine its rotating position.
[0028] (3) Rotation locking state: the fixed pin 5 is inserted into the rotation limiting hole 321 and the fixed slot, at this time the beam 2 and the mounting seat 3 are fixed, and the rotation position of the beam 2 is locked.
[0029] As a preferred solution, two bearings 4 are arranged on the mounting seat 3 for mounting the beam 2, and the midpoint of the axial connecting line coincides with the axial midpoint of the beam 2. By arranging two bearings 4, the mounting firmness of the beam 2 and the rotation stability of the beam 2 can be improved. Of course, the bearing 4 can be arranged as one or more than two, and two is the best design.
[0030] As a preferred solution, the mounting seat 3 includes two bearing mounting seats 313 and a pin mounting seat 323, the pin mounting seat 323 is arranged between the two bearing mounting seats 313, the bearing 4 is mounted on the bearing mounting seat 313, and the rotation limiting hole 321 and the angle limiting hole are arranged on the pin mounting seat 323.

The vacuum suction head is mounted on the bearing beam 22. The cross section of the rotating shaft 21 is circular, and the cross section of the bearing beam 22 is square. The bearing beam 22 is a telescopic structure. By adopting the above design, the production and installation are facilitated, and the bearing beam 22 is a telescopic structure. When the center of gravity of the hoisted object deviates in the length direction, the center of gravity can be adjusted by adjusting the length of the bearing beam 22, and the hoisting stability is improved.

By adopting the above design, the beam 2 is rotated to correspond to the insertion of the fixed pin 5 into different fixed slots, so that the beam 2 has multiple fixed rotation positions.
